SPECIFICATION forming part of Letters Patent No. 707,108, dated August 19, 1902.

Application filed September 16,1901; Serial Nd. 75,608. (no man.)

a certain new and useful Improvement in Car- Oouplers;and I declare the following to beafull, clear, and exact description of the invention, such as will enable others skilled in the,

art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates generally to car-couplers of the Master Car-Builders type,and more particularly to that class of such couplers in which a sliding pin locks the knuckle in its closed position.

In car-couplers of the type referred to when thelocking-pin is lifted outof the path of the tailpiece of the knuckle it is desirable that it should be supported in its unlocked position during the swinging of the knuckle to its open position'and'while the knuckle remains open, but permitted to automatically fall into its locking position in the path of the tailpiece of the knuckle when the latter is closed. j y

The object of my-invention'is to provide a car-coupler of the type referred to with means adapted to be positively actuated by the ele vation of the pinto engage and support the latter and adapted to be removed from its engagement with the pin by the tailpiece of the knuckle when the latter is open.

My invention as herein disclosed consists, essentially, in a car-coupler of the Master Car- Builders type,in which a vertical sliding locking-pin is supported in its elevated position prior to the opening of the knuckle bya pivoted dog, which isactuatedfthrough engagement with the pin to swing into supporting engagement therewith and to extendinto the path of'the tailpiece and which is removed from engagement with the pin by the tailpiece as the knuckle swings open, the pin being then supported upon the tailpiece until the knuckle is closed, when it falls into its looking position.

My invention will be more fully described hereinafter with reference to the accompanying drawings, in which the same is illustrated as embodied in a convenient and practical form, and in which-+ Figure 1 is a'vertical transverse section on line 1 1 of Fig."3,"s howing the pin in its looka ing position; Fig."*2,'a view similar to Fig. 1,

showing the pin supported in its elevated position by the pendulum-dog; Fig. 3, a vertical sectional view on line 3 3 of Fig. 1; Fig. 4, an enlarged perspective View of the locking-pin removed from the coupler-head, and Fig. 5 a

- perspective" view of the pendulum-dog detached from its cooperating parts.

The same reference characters are used to designate the same parts throughout the several figures of the drawings.

' Reference character Ajindicates the coupler-head, which isfpr'ovided with projections between which the knuckle B is pivoted, these parts being constructed in the usual manner. I h

B indicatesthe tailpiece of the knuckle, which extends through an opening in the coupler-head and engages the interior side wall thereof when the. knuckle is closed, as indicated in Figs.1'and3. The end of the tailpiece may be provided with a hook-shaped projection B which engages a vertical rib A projecting from the inner side or the coupler-head. The Iknuckle is retained in its closed position by means of the engagement of a locking-pin Owith the tailpiece B thereof. The lower end of the locking-pin G is provided with a cut-away portion 0 which when the pin is in'its lockingposition is engaged by a rib A ,'projecting from the lower wall of the coupler-head. .Ribs or flanges A, projecting from th'eflower'wall of the carcoupler head, serve as stops to prevent the lateral displacement of the locking-pin when it is subjected to strain through contact with is adapted to swing beneath, and thereby support, the locking-pin O, the portion E being.

cut away to form a projecting portion to ongage within the inclined groove 0 in the lower end of the locking-pin. The projecting portion E of the dog preferably inclines upwardly when beneath the locking pin, thereby obviating any liability of its being accidentally swung from beneath the pin. A lug E projects from the upper end of the dog E in the same direction as the lower portion E The lug E engages in a vertical groove G formed in the adjacent surface of the lockingpin G, the lower end of such groove being preferably upwardly inclined, thereby serving both as a stop to prevent the-removal of the looking-pin when it is elevated and also to positively swing the pendulum-dog into the position indicated in Fig. 2, in which the projecting foot portion E extends beneath the locking-pin in position to support the same. A finger E projects from the pendulum-dog near the upper end thereof and in a direction opposite to the lug E The finger E extends through an opening a in the coupler-head and affords a means for manually swinging the dog from beneath the locking-pin if it should be desirable to allow the locking-pin to fall into its locking position without opening the knuckle.

A perforated lug 0 projects from the upper end of the locking-pin, to which may be secured any suitable means for lifting the locking-pin when it is desired to uncouple the car.

The operation of my improved car-coupler will be readily understood from the foregoing description, in connection with the drawings referred to, and is as follows: When the locking-pin O is in the position indicated in Figs. 1 and 3, the tailpiece of the knuckle is locked in the position shown, thereby retaining the knuckle in its closed position through the interposition of the locking-pin 0 between the tailpiece and the ribs or flanges A, projecting from the lower wall of the couplerhead. When it is desired to permit the knuckle to swing to its open position, the locking-pin C is elevated through the connection of any suitable unlocking means with the lug C to the position indicated in Fig. 2. When the lower inclined end of the groove 0 engages the lug E further upward move ment of the locking-pin is prevented and the pendulum-dog E is pivotally swung into the position illustrated in Fig. 2, in which the foot projection E extends beneath the lower end of the locking-pin, and thereby supports the same. When the knuckle is swung openas, for instance, by the separation of the cars-the tailpiece B thereof engages the foot projection E of the pendulum-dog and removes the latter from beneath the lockingpin, which then falls upon the upper surface of the tailpiece of the knuckle and is supported thereon during the further motion of the knuckle to its open position while the knuckle remains open and until the knuckle is closed and the tailpiece thereof removed from beneath the locking-pin, which then falls by gravity into its locking position. (Shown in Fig. 1.) It should be noted that when the dog E is swung out of engagement with the locking-pin the latter falls a short distance to the tailpiece, so that the lower end of the coupling-pin is then below the level of the foot projection E on the dog, which cannot again swing beneath the locking-pin when the tailpiece is removed from beneath the locking-pin upon the closing of the knuckle.

If for any reason it should be desired to permit the locking-pin to resume its locking position after it has been elevated to its unlocking position without opening the knuckle, pressure may be applied to the finger E, which extends through the coupling-head to the exterior thereof, and the dog E thereby swung on its pivot e from the position shown in Fig. 2 to that indicated in Fig. 1, which permits the locking-pin C to fall into position to retain the knuckle closed.

From the foregoing description it is evident that I have devised a car-coupler of the type referred to in which the locking-pin is held in its raised or unlocked position by a device which is engaged by the pin during its upward movement and positively moved into supporting engagement therewith.

I do not claim herein, broadly, a car-coupler provided with a pivotally supported dog adapted when the locking-pin is elevated to swing into supporting engagement therewith, such dog projecting into the path of the tailpiece of the knuckle, whereby it is removed from its supporting engagement with the locking-pin when the knuckle is swung from its closed to its open position, as such invention is claimed, generically, in my pending application,Serial No.29,523, filed September 10, 1900.

While I have described more or less precisely the details of construction, I do not wish to be understood as limiting myself thereto, as I contemplate changes in form, the proportion of parts, and the substitution of equivalents as circumstances may suggest or render expedient Without departing from the spirit of my invention.

Having now fully described my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. In a car-coupler, the combination with a coupler-head, of a knuckle pivotally supported therein, a locking-pin for said knuckle, means located on the opposite side of the locking-pin from the tail of the knuckle when the latter is in its closed position and engaged by the locking-pin when it is elevated and moved thereby into position beneath the pin to support the same, substantially as described.
